1.0 Introduction This manual describes how to install, test, and service the Centeron Tank Console (hereafter referred to as the Console). The Console is part of the Centeron Level Monitoring System, which includes the Console and up to ten Monitors. This guide does not include how to install, test, maintain or troubleshoot the Monitors. Refer to the Monitor s instruction manual for its installation and maintenance. The description herein is based on a standard installation. The Console is to be installed as fixed, permanently connected equipment. This means that the Console should be fastened to a support and electrically connected to its 110 VAC supply by a permanent connection which can be detached only by the use of a tool. 2.0 Product Overview 2.1 Description The Console is a receiver that contains a local database of Monitor information. The user programs the Console with tank and Monitor configuration data. The Console processes the readings from the Monitors and displays the level and status of the tanks on the Console s display. 2.2 Operation The Console receives data from a Monitor using RF transmissions. The Level Monitoring System utilizes spread spectrum technology for communication in the 902 928 MHz band in accordance with the Federal Communications Commission s (FCC) Rules. The Console processes the data received from the Monitor and displays the level in the tank based on the data reported by the Monitor. The user must set up the Monitor in the Console s database before the Console will process the Monitor s data. Appendix A details the method for configuring monitors in the Console s database. The user can scroll through the monitor database using the Tank Console s pushbutton. 2.2.1 Display Data The Console s display is separated into three sections for tank data: Level Data, Tank ID, and Tank Status. See Figure 1 for the location of each of the data fields. Robertshaw Industrial Products Page 1

Refer to the Monitor s installation manual regarding the correct battery type and the battery installation procedure. The Console hasn t received a transmission from the tank s Monitor within the appropriate transmit interval. Refer to the Monitor s manual for troubleshooting tips. The tank s Monitor is operating normally. 2.3 Environmental Specifications The following environmental specifications should be observed when installing the Console: Temperature Range: -40 o C to +60 o C Designed for indoor or outdoor use. The NEMA 4X housing is designed to protect the Console circuit board. Chemical Exposure: The Console is housed in a NEMA 4X housing. 2.4 Certifications This equipment complies with Part 15 of the FCC Rules. 2.4.1 FCC Notice Radio Frequency Communications The Console generates and uses radio frequency energy. If not installed and used in accordance with the manufacturer s instructions, it may cause interference to radio and television reception. The Console has been tested and found to comply with the specifications in Part 15 of Radiators and FCC Rules for Class A Digital Devices. CAUTION: Robertshaw Industrial Products does not support field changes or modifications to any of the Centeron Level Monitoring System equipment unless they are specifically covered in this manual. All adjustments must be made at the factory under the specific guidelines set forth in our manufacturing processes. Any modification to the equipment will void the manufacturer s warranty and could void the user s authority to operate the equipment and render the equipment in violation of FCC Part 15, Subpart C, 15.247. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) Robertshaw Industrial Products Page 3

this device must accept any interference received, including interference that may cause undesired operation. 2.4.2 Canada This Class A digital apparatus complies with Canadian ICES-003. Cet appareil numérique de la classe A est conforme à la norme NMB-003 du Canada. 2.4.3 Safety and Regulatory The Console complies with UL 61010B-1 Electrical Measuring and Test Equipment; Part 1. 3.0 Installation 3.1 RF Site Guidelines The Console may only be installed vertically with the writing on the front panel upright. The following guidelines will ensure the optimal RF link between the Monitor and the Console. Direct line of sight between the Monitor and Console will provide optimum radio reception. The Monitor and Console can communicate at distances up to one mile under optimum line-of-sight conditions. When obstructions such as walls, buildings, and vehicles exist between the Monitor and Console the distance between these units should be limited to less than 500 feet. Multiple obstructions (such as two or more walls or a tank and a wall) between the Monitor and Console should be avoided, if possible. Electrically conductive objects such as metal buildings, concrete reinforcement rods, tanks, silos, and vehicles reflect radio signals. This reflection can be either an advantage or disadvantage to good radio reception at a particular installation site: 1. Metal objects between the Monitor and Console may reflect and scatter RF energy and reduce radio signal strength at the Console. 2. Metal objects behind the Monitor or Console may increase the radio signal strength at the Console by reflecting radio signals toward the Console. Robertshaw Industrial Products Page 4

Even small metal objects such as tank vents or toolboxes between the Monitor and Console can significantly reduce radio signal strength if they are within a few feet of the Monitor or Console. These objects can reflect radio signals and cause a RF shadow which may prevent radio signals from reaching the Console. Objects which are not electrically conductive such as wooden or fiberglass buildings, non reinforced masonry, trees, plastic, and glass have less effect on radio signals than metal objects. Windows and wooden doors can provide radio signals access into otherwise closed metal buildings. However, low-e window glass may have a thin metallic coating which can reflect radio signals. Strong electromagnetic fields such as those found in close proximity to power lines, large electric motors, generators, electric fences, and transmitter antennas may interfere with the radio signals received by the Console. The Console should be mounted as high as is reasonably possible to improve its ability to receive radio signals. Warning: For maximum Monitor reception, mount the Monitor within 500 feet of the Console, avoid mounting either device inside a fully closed metal building, and avoid close proximity to large electrical equipment. 3.2 Handling and Cleaning Guidelines The Console should be handled with care. The electronics inside of the enclosure are static sensitive. Do not handle the electronics outside of their enclosure without proper static precautions. The Console should only be cleaned by wiping it with a water-dampened cloth on an as needed basis. No other method should be used. 3.3 Mounting 3.3.1 Site Selection Select an area for mounting with an available 110 VAC supply in the same physical area. Follow the RF site guidelines outlined in Section 3.1. Choose a mounting location in accordance with good instrument practice, avoiding extremes of temperature, humidity, and vibration. Robertshaw Industrial Products Page 5

3.3.2 Mounting The Console must be rigidly mounted to a support in a fixed location. When mounted, the writing on the cover of the Console should be upright. All directions (top, bottom, left, right) are with reference to this orientation. The Console should be mounted using four (4) #8 panhead screws in the enclosure s mounting holes. The Console does not require a minimum spacing for ventilation around it. However, proper spacing may be required to allow easy access to and use of the disconnecting device described in the wiring section. 3.3.3 Wiring Before wiring, unscrew the front cover from the enclosure. If necessary to simplify wiring, disconnect the cables connecting the front cover electronics to RS-232 connector. Store the cover assembly in a safe place during wiring. All wiring must conform to the NEC and any applicable state and local codes. All wiring connections are labeled on the Display/Supply Board. The requirements for wiring to the Display/Supply connectors are given in Table 3. Table 3: Display/Supply Board Connector Requirements Connector Designators Wire Requirements Tightening Torque TB1 12 AWG, maximum, rated 9 in-lbs for 80 C, minimum Wiring for power (hot, neutral, and earth ground) should be routed through conduit into the bottom right hole in the enclosure. The installer must install an external switch or circuit breaker to provide a means to disconnect the Console from power. The external switch or circuit breaker must be marked as the disconnecting device for the Console and its installation must conform to all applicable codes. The power connections as labeled on the Display/Supply Board at TB1 and are described in Table 4.
